1. A multi-sense platform, comprising:
a first sensor;
a second sensor; and
a controller disposed in signal communication with the first sensor and the second sensor,
the controller being configured to;
using a combination of readings from the first sensor and the second sensor to determine a presence of a first type of gas based on readings of the first sensor and to distinguish between a first one of the first type of gas and a second one of the first type of gas based on readings of the second sensor, wherein readings of the first sensor cannot distinguished between the first one of the first type of gas and the second one of the first type of gas; and
categorize unknown chemicals as one or more of potential hazardous air pollutants (HAPs), uncategorized volatile organic compounds (VOCs), and low-risk VOCs.
